Lithium ion batteries are quintessential components of modern life. They are used to power smart devices — phones, tablets, laptops, and are rapidly becoming major elements in the automotive industry. Demand projections for lithium are skyrocketing with production struggling to keep up pace. This drive is due mostly to the rapid adoption of electric vehicles; sales of electric vehicles in 2020 are more than double what they were only a year prior. With such staggering growth it is important to understand how lithium is sourced and what that means for the environment. Will production even be capable of meeting the demand as more industries make use of this valuable element? How will the environmental impact of lithium affect growth? This thesis attempts to answer these questions as the world looks to a decade of rapid growth for lithium ion batteries.

Health service quality is understood to be a crucial determinant in successful patient-physician encounters and patient health. One common feeling that patients have reported experiencing during appointments is shame. We hypothesized that patients who experience appearance-based shame during an appointment are not likely to return to the same physician and that patients who do not experience appearance-based shame are likely to return to the same physician. This was assessed by conducting an anonymous online survey of 13 questions that served to establish a general foundation for understanding the participants' physical characteristics such as race, age, weight, and gender identity as well as their overall patient-physician relationship and experiences of shame, if applicable. 119 participants were recruited from Arizona State University and a case study was performed individually for five participants of interest. The data analyzed from this study suggests that while appearance-based shame does exist in healthcare spaces, it is not a significant determining factor in patients returning to their physicians. In addition, there was no significant evidence to suggest that patients who do not experience appearance-based shame are either likely or more likely to return to their physician. We hypothesize this could be due to confounding variables such as convenience, accessibility, or insurance limitations which patients may prioritize over feeling ashamed during an appointment. However, more research needs to be conducted to confirm these hypotheses.

As educational tactics circulate globally, so too does the prospect of understanding sustainability amongst informed individuals and what it means for our society. Just in the past few decades, the environmental movement has changed the way in which people think about their own impact upon the planet. It is becoming a facet of common knowledge for society to realize the potential detriment of their actions, and for this, we should be grateful. However, there is much work to be done regarding all aspects of sustainability and environmental crises. This paper offers a look into the world of sustainable sunscreen usage, something that is not often thought about as an aspect of sustainable consideration. The task of this research opportunity was to examine a sample of survey respondents and connect their responses from 15 questions to different hypotheses. Alongside the discussion of sunscreen filters damaging sensitive ocean ecosystems, this research also looks into the overall importance of sunscreen for one’s health and the ways in which it can be used safely. My hope is that readers will realize the value of using sunscreen on a daily basis and become better informed of sustainability challenges and healthcare disparities.
